    3. Select the desired region and find the security group.
    4. Locate desired security group and click Modify Rules. The Security Group Rule page then appears.
    5. Use Inbound rule and Outbound rule to switch between inbound and outbound security group rules.
    6. Locate the desired rule and click Edit to modify it.

      You don’t need to reboot the CVM for the rule changes to take effect.
